Spectrally resolved optical frequency comb from a self-referenced 5 GHz femtosecond laser

In this paper, a self-referenced Ti:sapphire femtosecond laser frequency combs (FLFC) with 5 GHz repetition rate and 230 pJ of pulse energy is reported. The individual modes of the 5 GHz FLFC are dispersed and recorded in a 2D image using a high-resolution spectrometer. This experiment is an important milestone within ongoing efforts to investigate applications in spectroscopy and arbitrary waveform generation with well-stabilized mode-locked femtosecond lasers.
